Talk:SafeDisc

There is currently (as of 2006) no known technique that can successfully burn a disc.

You're right. This was probably in reference to DVDs. Afaik, there is no known burner that is able to burn a SD4 DVD. Nil Einne 13:11, 15 August 2006 (UTC)

I took the liberty of deleting the useless information stating what can be burned with what tools under the V4 header. The information is useless as it's not information about Safedisc, or even how to circumvent it. The information may also be considered to be illegal. —Preceding unsigned comment added by 62.163.0.80 (talk) 23:48, August 25, 2007 (UTC)

With regards to merging the topics, I think the merger should go ahead. Whilst googling safedisk and the number of results being returned is roughly equal to safedisc, Macromedia call their technology SafeDisk as per:

same here safedisk is a misspellingCartoonborg 01:02, 7 December 2006 (UTC)

They call it SafeDisc, you mean. Merge it. Regenspaziergang 10:44, 16 December 2006 (UTC)

SafeDisk (v4) needs a quick cleanup.

Potential Hardware Damage

I'm surprised there is no mention here of the blown speaker incidents. The odd data sends square waves that can destroy some speakers. —The preceding unsigned comment was added by Zerothis (talk • contribs) 10:37, 14 January 2007 (UTC).

You cant play safedisc on a redbook cdda player the cd contains data not audio frames Cartoonborg 21:34, 14 January 2007 (UTC)

Legal accountability

The lawsuit (and settlement) against Sony BMG was based in large part on the security risk that their DRM rootkit presented. This article states that the SafeDisc driver grants ring 0 access to the kernel, so it looks like SafeDisc could also be defeated by way of legal remedies. 24.6.99.30 00:47, 20 February 2007 (UTC)

Vulnerabilities

"SafeDisc installs its own Windows device driver to the user's computer, named secdrv.sys."

secdrv.sys is one of the pre-installed XP device drivers, so it's possible that SafeDisc just uses a Windows driver that is already there. Do you mean that SafeDisc replaces the Windows device driver with its own version of secdrv.sys? Is it possible that SafeDisc installs secdrv.sys only on Windows versions that did not have secdrv.sys installed?

Please write a more detailed description of how you think this works.

I deleted the section on vulnerabilities. Anyone with knowledge of the internal workings of the driver can tell you this is a load of bollocks. Unless you manage to find a way to elevate by reading a debug-register or something similar to that, there is no way to exploit this driver. The secdrv driver is a part of safedisc though, even through a version ships with Windows. —Preceding unsigned comment added by 62.163.0.80 (talk) 23:43, August 25, 2007 (UTC)

I added a sentence to the vulnerabilities section because as it stood, it was misleading, implying that the vulnerability that Microsoft had announced on Nov 7 2007 was still open, and it's not - it was patched on Dec 11 2007. --59.167.55.49 (talk) 08:24, 2 December 2008 (UTC)

SafeDisc Lite?

Dungeon Siege has a variation of SafeDisc apparently called SafeDisc Lite. I spent almost a year trying to get help from Microsoft because inserting the DS CD into my notebook would cause violent vibration and rapid overheating to the point that my notebook would sound an alarm and switch off within 20 seconds. All their solutions started with "Insert the CD" (duh, did they even read my email?). Eventually they shocked my by sending a set of replacement CDs without copy protection. They are marked with huge inverted print "DO NOT COPY" and licensing warnings all over. Hopefully this is a trend, providing undamaged disks when customers request them.

Pasted in

The Versions section of the page seems to be pretty much pasted in from CD Media World, minus a few sentences here and there:

Can someone else reword the section? Cipher42 04:49, 30 July 2007 (UTC)

is C-Dilla a subdivision of Macrovision ?

when i look who have made the clokspl files ... the company name that show up is C-Dilla SafeDisc....

Copyright (c) C-Dilla Ltd 1997-1998 for SafeDisc 1.0

what do you think about that ?

C-Dilla was the company which originally made Safedisc, before they were bought by Macrovision. —Preceding unsigned comment added by 213.88.221.1 (talk) 13:00, 18 October 2007 (UTC)

Safedisc and safecast discontinued?

I have noticed that Rovi Corporation has bought out Macrovision, and safedisc and and safecast are no longer on its website. Also, a scene group released a tool and in its nfo it states "Since the Macrovision Corp. turned into Rovi Corporation and discontinued development of SafeDisc/SafeCast DRM's, we have decided to make this old tool public (after some adjustments).". Can anyone confirm this for me? Ub3rst4r (talk) 00:47, 29 October 2009 (UTC)
